Shell U.K. Limited Enhances Well Planning

Fully integrate workflow so that the drilling

and G&G teams can access all informationto collaborate and better anticipatedrilling issues.Solution

Use Petrel* drilling workflow to gather

knowledge and lessons learned to performwell planning and optimization tasks.The following modules were used.

Shell U.K. Limiteds G&G team and reservoir engineers were routinely using the Petrel workflowfor drilling, but the drilling engineers were not.Schlumberger proposed implementing a single multidiscipline solution to be used by all. The powerof Petrel seismic-to-simulation software enables collaboration by all partiesincluding geologists,geophysicists, drillers, reservoir engineers, and production engineersin the same shared earthmodel. Schlumberger demonstrated that the solution would be very useful for the drilling engineersand that including them in the unified workflow would benefit the entire team.Using a single workflow process powered by Petrel software improves the planning workflow aswell as optimizing well placement and drilling operations.

Solution requirements

Petrel geology core

Petrel drilling visualization

Shell U.K. Limited articulated its requirements, which included the following points.

Petrel petrophysical modeling

Facilitate data/knowledge transfer across the whole subsurface team

Petrel data analysis

Help the drilling team to work in a proactive mode using real-time data

The project was accomplished in 11 days, delivering great added value

in a short time. The Petrel drilling workflow helped the drilling team towork in a proactive mode and better anticipate problems that could leadto nonproductive time or less-than-optimal reservoir contact. It alsoenhanced collaboration between disciplines, including the drillingengineering staff, because it provided a common collaboration platformfor the subsurface team. The platform offers

powerful drilling parameter predictions with automation capabilities

well path optimization and drilling time estimation

KPI analysis capabilities.

ROP-WOB prediction versus real-time acquisition.

During the execution phase, real-time data was superimposed on the

modeled data, which showed very good agreement, indicating thatmodels were quite predictive of the actual reservoir drilling conditions.
